I'm very happy with the jumbo hooded litter box. I have 3 grown female cats using the box and very small amount of litter escapes and probably wouldn't have any if I left the flap down. I just leave it laying on the top because of one of my cats. She is untrusting of anything new but I'm sure she will adjust. Anyway, it is so much nicer then the old one and a lot less work for me! Thanks!!!!
